Skew

Overview
POLE – SKEW design area
1 Selection of the ROTOR subset: POLE panel (click on the icon POLE)
2 The Skew tab indicates the tool to define the pole skew angle
3 Visualization of the machine radial view to visualize the pole skew
4 Visualization of the rotor developed view to visualize the pole skew
5 Choices to define a skew: None – Continuous (Continuous in our example)
6 Skew inputs to be defined
7 Buttons to restore the default input values.
8 Buttons to validate the inputs (pressing the “enter key” twice applies inputs too).
9 Skew outputs (read only)
10 Button to export the skew data into *.txt or *.xlsx files.

Set a skew angle
How to set a skew angle?
1 Choose the definition mode of the skew: Stator slot – Rotor slot – Shift angle
2 Definition of the skew angle, depending on the definition mode
3 Visualization of the chosen skew angle on the machine radial view
4 Visualization of the equivalent axial slot angle on the rotor developed view
5 Equivalent axial rotor slot angle (read only)
6 Equivalent stator slot pitch (read only)
7 Equivalent rotor slot pitch (read only)
Note: The user can add a skew angle on the rotor or on the stator. If a skew is already defined in the stator when setting a skew on the rotor, the stator skewing will be automatically reset to “None”.
